Alexander Borodai, the leader of the pro-Russian separatists in the Ukraine, has compared the MH17 disaster zone to "black humour" in an interview with CNN.

Borodai, the self-styled Prime Minister of the Donetsk People's Republic and leader of the separatists accused of shooting down Malaysia Airlines flight MH17, was discussing the process of moving the bodies of the 298 victims of the disaster.

He claims that the Organisation for Security and Co-operation in Europe (OSCE) advised the armed separatists not to move the bodies.

"As soon as members of OSCE arrived, they notified us that as soon as we start moving the bodies then we will be responsible," Borodai said.

"It got to the point where it resembled if not a horror movie, then black humour."

"When an old woman comes to our rebel groups and say, look there is a body of a headless man, [He] fell straight on my bed, please take this man away - the rebels say no, because they are following international instructions," Borodai said.

The OSCE denies ever advising the Russian separatists on such a course of action.

Throughout the interview, Borodai rolled his eyes at the weight of public opinion and dismissed all the evidence of Russian separatists involvement in the crash.

"It is very simple to disprove it. All of the information that comes through the internet is practically all lies."

Borodai rejected the veracity of the tweets posted immediately after the crash by his own separatist officers.

His contempt for the internet was matched by his disdain for probing interview questions.

The Russian separatist leader's dismissive body language suggested he had little time for questions on the whereabouts of the black boxes, Russia's involvement with the catastrophe, or the weapons used to bring down MH17.

"I am telling you again, we have never been in possession of a single BUK [surface-to-air missile] system," he said.

"I can list all of the means of defence that we have. All of these means of defence are capable of only crashing low flying targets."

Despite welcoming international observers to the crash site, Borodai pointed the finger squarely back at Ukrainian interests in bringing down the plane.

"We didn't have any motives to target these planes, but for Ukraine our enemy, the crash of this plane is very beneficial," said Borodai.

A preliminary US intelligence assessment indicates that the Malaysia Airlines plane that crashed in eastern Ukraine was shot down by an anti aircraft missile fired by pro-Russian separatists, a US official said last week in Washington

"Our assessment is that Malaysian Airlines Flight 17...was likely downed by an SA-11 missile, operated from a separatist-held location in eastern Ukraine," US Ambassador to the United Nations Samantha Power told the UN Security Council.
